Let's keep track of bugs and "gotcha's" that we find in the ICS leak or any apps that have problems with the ICS leak.
Bugs/Problems [Updated 4/4/2012]
TwLauncher crashes almost immediately after install (Crashes seem to stop after using the phone for a bit. Possible Workarounds: factory reset; re-flash ROM again)
Some applications seem to lag worse than on GB, noticeable scroll and transition studder
Black crush issue still exists but was "addressed" (test image with 1-21 blocks, on GB it dropped to black on "1", on ICS it drops to black on "7" and it's still not gradual)
Noticeable grey-to-black banding, transition is not gradual

Application Problems [Updated 4/4/2012]
Nova Launcher/Apex Launcher works but can't add widgets due to "Not enough space on this Home page" (The widgets are actually 6 columns wide. Workaround: Nova Settings > Behavior > Enable Resize all widgets, then go to Desktop > Desktop Grid > Set columns to 6, add widget to the home page, resize the widget to take up only 5 columns, go back to Desktop > Desktop Grid > Set columns to 5)
